To be honest the Original 70's versions sucked. The updated one were much better other then the fact that gweedo shot first.
Sucky bits in the revamped trilogy:
1) Greedo shoots first.
2) The entire Jabba the Hut scene in Ep4
3) The jawa falling off some beast on the way into the city
4) The changed ending in Jedi
There are a few bits that are questionable (redubbing Boba Fett's voice, the snow monster scene in Empire), but they're not absolutely stupid. But yes, otherwise the cleaned up versions are much more "watchable".
But the originals, warts and all, need to be available for film history reasons.
And based on that link -- screw Lucas. I won't buy them. There's absolutely no reason to go back to the Laserdisc version -- they did a
lot of restoration prior to the changes they made in the 90s, and you don't think they have that restored footage available? In high-resolution, digital, anamorphic format? Yeah, and I've got a bridge to sell you too.
Haven't bought them on DVD yet, so I guess I'll just keep on with that. Screw it.
Oh, and the list price for the DS Lite appears to be $129 in the US (based on a number of stores offering pre-orders for it at that price). Best deal isn't that $119 -- get it from Target or Buy.com and use a 10% off coupon. Depending on shipping, that may save you a few bucks.
Or wait for it to actually come out and see what the weekly ads are then. The only reason to pre-order is if you think it's going to sell out for weeks on end.
